You want to avoid HVAC repair in Fresno, CA as much as possible. Even though fall has now officially arrived, the Central Valley is still experiencing blistering hot days that can reach the 90s. Your home’s air conditioning system has hard work ahead, and if you aren’t cautious about running it, you may drive it into the ground and cause an expensive repair or replacement.
Your air conditioner has limits. For example, the AC can’t lower the temperature in your house to the point where water would freeze. (Not that you would want to.)

Two-story homes often encounter problems with their upper floors getting much warmer than the lower floors. Heat rises, so heat tends to gather in the upper levels of a house. Another cause is heat coming through the roof on sunny days. A hot upper floor can happen even in a home with a powerful heating and air conditioning system and well-designed ductwork, and it can occur at any time of the year. However, ineffectual ducts and malfunctioning comfort systems can contribute to the problem.
